Product Information

SSD1815T1 Development Kit

DVK1815T1-A0 is a demonstration of SSD1815T1 working on a (132 X 64 +
1 icon line) panel. It is intended to help users expedite their design-in of
SOLOMON LCD driver.

PACKAGE CONTENTS

DVK1815T1-A0 consists of the following:

1) LCD Module (132 X 64 + 1 icon line) (DVM1815T1-A0)

2) LCD Drawing (optional)

3) Programmed 8051 MCU Board (EVM89C52-A0)

4) 8051 MCU Board Schematics (EVM89C52-A0)

5) Demo Program in C Language (PRG1815T1-A0)

SYSTEM REQUIREMENT

DVK1815T1-A0 is good enough to serve as a standalone demo. 2 X AA 1.5V
battery is required for normal operation. For engineering evaluation on the LCD
driver and/or LCD panel, a 8051 Incircuit emulator (ICE) is required. The one
Solomon Systech is using is EMMIT 8051 ICE from Syber Electronics Co Ltd.

The LCD module has been configured as follows

1) size: 132 X 64 + 1 icon line

2) TAB Package

3) 4X DC-DC converter to generate VEE

4) Internal feedback resistor which is software programmable is used to
generate VL6.

5) 6800 8-bit parallel interface.

6) 24 pins single inline (SIL) header is used to connect 8051 MCU Board to LCD
Module. Please refer to Table 1 for pin assignment.

8051 MCU BOARD

The 8051 MCU Board is powered up by 2 X AA 1.5V battery. A 2X DC con­verter (ICL7660) is used to generate 4.8V to supply 8051 MCU. This voltage is
also regulated by LM317 to generate VOUT (adjustable from 1.8V to 3.5V)
which in turn powers up solomon LCD driver. All logic output from 8051 are
down-converted from 4.8V to VOUT through 74HC4050 non-inverting buffer.
User can change VOUT by tuning T1 (1K trimmer).The MCU board is configured
to run at a speed of 4MHz. 4 dummy keys are reserved for developing user­interactive application such as tuning contrast.
